When does a garage roof in Worthing need replacing?
A garage in Worthing that is becoming a workshop, gym or home office is a good reason to replace its roof. That is the moment to think about insulation and a warm-roof build-up, so the roof does not have to be stripped again when the space is heated.
In and around Worthing, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, and on shops with flat-roofed rear stores below flats. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a new garage roof cost in Worthing?
At South East guide rates, a typical 18 m² garage roof in EPDM comes to £1,750–£3,100 including VAT. The fixed price comes after a free survey for new and replacement roofs.

What if my garage roof is asbestos cement or old felt?
If your garage has corrugated cement sheets, especially on a pre-2000 building, assume they could contain asbestos until a test says otherwise. We do not remove asbestos; any suspected material is tested and, if confirmed, removed by a licensed specialist before our work starts.
Once the old sheets have gone, the garage usually needs new timber joists or purlins and a deck before a membrane can go on. Old felt garages are more straightforward: the felt is stripped and the deck assessed in the usual way.
Lock-up blocks and rows of garages bring their own issues. A shared roof often has several owners, so we can quote per bay, or for the whole run where everyone agrees, which keeps the edges and joins between garages consistent. Attached garages need careful upstands and flashings where the roof meets the house wall, while detached ones are about edges, gutters and falls.
Not sure whether your roof needs replacing? Our guide to repair or replace sets out the signs.

Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a new garage roof cost in Worthing?
£1,750–£3,100 for a typical 18 m² garage roof in EPDM, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Do I need to empty my garage before the roof is replaced?
It helps to clear valuable or delicate items, and to cover the rest with dust sheets. Debris can fall through gaps in an old deck during strip-out.
Can a garage roof be replaced in one day?
A small single garage with a sound deck can often be stripped and re-covered in a day. Deck repairs, a double garage or poor weather can stretch it to two or three.
